QUESTION 1 To study how proteins fold, scientists must be able to purify the protein of interest, use solvents like urea to denature the folded protein, and observe the process of refolding at successive time points. What is the effect of the solvents used in the denaturation process? a. The solvents break all noncovalent interactions. b. The solvents break all covalent interactions. c. The solvents create a new folded conformation. d. The solvents break some of the noncovalent interactions, resulting...

Study the interaction between proteins and DNA in more than 100 protein-DNA complexes. Arginine: A-7 T-5 G-26 C-1 Glutamate: A-? T-? G-1 C-11 Tryptophan A-? T-? G-? C-? Explain why you could not find any single bonds between tryptophan and one of the DNA bases. Explain why you found single hydrogen bonds between glutamate and some of the DNA bases. Is there a preference of arginine for one of the amino acids?

1. What was the significance of Photo 51? 2. What causes there to be a major and minor groove? What is the difference? 3. Which groove contains more “information” and why? How do proteins interact specifically with this DNA groove, as when a zinc finger crosses the groove? 4. Which of the following base pairs could proteins distinguish, and why? a. Major groove base pairs (GC/CG, AT/TA, GC/TA, GC/AT) b. Minor groove base pairs (GC/CG, AT/TA, GC/TA, GC/AT) 5. Where...
